SPECIFICAT 0N forming part of Letters Patent No. 499,146, dated June 6,1893.

Application filed February 6 1893. Serial No. 461,198. (No model.)

To all whom it may concern.-

B e it known that I, HORACE TOM ROGERS, a citizen of the United States,residing at Loulsvllle, in the county of Jefferson and State ofKentucky, have invented a new and useful Belt-Clamp, of which thefollowing is a specification.

This invention relates to belt clamps, and has for its object to providea new and improved device for tightening belts, especiallyelevator-bucket belts, and giving them the required tension, or to beused in connecting the two ends of a belt; and with this end in V ew theinvention consists of the construction and arrangement of the partsthereof as wlll be more fully hereinafter described and claimed.-

In the drawings: Figure 1 is a perspective view of an elevator belt box,showing the belt therein and the improved device applied thereto and asbeing operated to draw the two ends of the belt together, the partsbeing broken away. Fig. 2 is a longitudinal vertical section on the line0cm of Fig. 1. 1s a perspective View of the clamp detached.

Similar numerals of reference indicate corresponding parts in theseveral figures of the drawings.

Referring to the drawings, the numeral 1 designates a hollow head,having oppositelysituated open sides and upper and lower closed ends.The said head is also formed with an inner flat plate 2, that closesover the same and has, at the upper end thereof, a pair of ears 3,extending at right angles therefrom and formed with slots 4, that openinward into the same from the upper edges thereof, as shown positionedin Fig. 1.

Extending longitudinally through the head 1, is a shaft 5, having thegreater portion thereof screw-threaded as at 6, but that portion of theshaft which is located within the head 1 is smooth and has fixed thereona beveled gear 7, with an elongated sleeve 8, formed with acircumferential groove 9, that is engaged by the wall of a circularopening in the upper end of the said head to thereby form a bearing forthe said shaft, it being understood that the said beveled gear 7 iskeyed to the latter. The beveled gear.7 is engaged by a thereto, and hasattached to the same a crank or operating-handle 11, by means of whichthe gear 10 is operated to actuate the gear 7, with which it meshes andconsequently operates the said shaft 5.

Adj ustably mounted on the screw-portion 6 of the shaft 5- is anotherhead 12, having a screwthreaded apertured lug 13, through which the saidportion 6 of the shaft has move-- ment, and is also provided with a fiatplate 14, having ears 15 projecting inwardly therefrom at right anglesthereto with open slots 16 extending through the lower edges thereof.The ears 15, with their slots 16, are in all respects similar to theears 3 with their slots 4, in connection with the head 1, and it will beobserved that the slots open outwardly from each pair of ears 3 and 15in such manner as to have their entrance portions opposingly situated. 7

In each pair of cars 3 and 15 is loosely and removably mounted a clamp17, having a lower or outer roughened or serrated biting-edge 18, andthe opposite end of the edge reduced in width to form anoperating-handle or grip 19. The opposite ends of the clamp are formedwith trunnions 20, that have bearing in the slots of the ears 3 and 15,in each instance, but are freely movable when it is desired todisconnect the clamp, but when it is necessary to hold the clamp inconnection with the ears itwill be retained in position by the tensionof the belt thereon, it being observed that said tension will be exertedin such a direction as to draw the trunnions, and consequently the clampcarrying thesame, farther into the slots.

As the clamps are loosely supported by the ears, it is necessary toprovide some means of holding them attached to the device to prevent thesame from becoming lost, and therefore a chain is secured to thegrip-portion of each clamp, as at 21, by means of rings 22, and to oneof the adjacently-situated ears, it being understood that the chain ineach instance is sufiiciently long as to permit the free manipulation ofthe clamp. 1

In setting the device up in proper position, it is secured to one sideof an elevator box22, having a suitable opening therein through whichthe ears carrying the clamps are projected, as shown in Fig. 1, and inthis position the plates 2 and 14 bear firmly against the side of theelevator box and hold the device in position in a proper manner.

It will be understood that this device is especially intended for usewith elevator belts, and to hold the belt in perpendicular positionduring the operation of tightening or fasten ing the same.

In operating the device the opposite ends of the belt are first put inposition on the machine and rest against the flat plates 2 and 14, thatform tables therefor and lie between the ears 3 and 15. The clamps arethen inserted in position and drawn tightly against the belt to hold thetwo parts thereof in connection with the machine. The crank-handle isthen operated to turn the shaft 5, and the screw-threaded portion 6thereof is caused to draw the head 12 toward the head 1, and

thereby clamp the two parts of the belt in close position either for thepurpose of tightening the same or joining the said ends.

It will be understood that in making the attachment to the opposite endsof the belt the head 12 is adjusted as far from the head 1 aspossib1e,'in order to conveniently make the attachment of the said head12 with the opposite belt-end. It will also be understood that theplates 2 and 14 will be constructed of varying widths and sizes in orderto accommodate different sizes of belts, butit will be seen that onemachine or device can be employed with varying sizes of belts if thesize thereof is of such dimension that in each instancea thoroughgripping-action is provided by the clamps.

Having described the invention, what is claimed as new is In a device ofthe character set forth, the combination of the two heads, one of whichhas a screw-threaded shaft extending therefrom and operating mechanismfor revolving said shaft, and the other movably mounted on saidshaft,each of said heads having a pair of ears extending at right anglesoutwardly therefrom with slots therein that open outwardly from theedges of the ears toward each other, and flat plates adjacent to saidears, and clamps loosely mounted in and freely removable from the saidears and having chains secured thereto and to adjacent ears to hold thesaid clamps in attachment with the device, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

HORACE TOM ROGERS.
